Unit 5 APES

Front

What is the O horizon in soil composition?

Back

The O horizon is the top layer of soil, composed primarily of decomposed organic material, and is most pronounced in forested areas.

Front

Describe a convergent boundary in geology.

Back

A convergent boundary is where tectonic plates push towards each other, leading to subduction, the formation of volcanoes, and causing earthquakes.

Front

What is Horizon C in soil profiles?

Back

Horizon C is the layer of soil that consists of partially weathered rocks.

Front

Define ore in the context of geology.

Back

Ore refers to commercially valuable deposits of concentrated minerals.

Front

What geological event is commonly associated with convergent boundaries?

Back

Earthquakes are commonly associated with convergent boundaries.

Front

What is the significance of the O horizon in ecosystems?

Back

The O horizon plays a crucial role in nutrient cycling and supports diverse plant and animal life due to its rich organic content.

Front

What processes occur at convergent boundaries?

Back

At convergent boundaries, processes such as subduction, mountain building, and volcanic activity occur.

Front

What is the role of Horizon C in soil formation?

Back

Horizon C serves as the parent material for the upper soil horizons, influencing their composition and characteristics.

Front

How do earthquakes occur at convergent boundaries?

Back

Earthquakes occur at convergent boundaries due to the stress and friction generated as tectonic plates collide and interact.

Front

What types of minerals are typically found in ore deposits?

Back

Ore deposits typically contain valuable minerals such as gold, silver, copper, and iron.
